Hi there, I'm getting lots of CIFS errors in my system log: Jan 30 08:46:05 Server1 kernel: [747319.264235] CIFS VFS: Send error in Flush = -9 Jan 30 08:46:05 Server1 kernel: [747319.264235] CIFS VFS: Send error in Flush = -9 Jan 30 08:46:05 Server1 kernel: [747319.264235] CIFS VFS: Send error in Flush = -9 Usually 10-20 messages will appear at once like this. This had happened occasionally when I was on Ubuntu 12.04 LTS, but since upgrading to Ubuntu 13.10 they are appearing daily (I actually upgraded to get a newer version of cifs-utils in the hopes that the problem would go away). Modinfo cifs shows cifs.ko at version 2.01, and cifs-utils is at 6.0. The share is mounted via fstab: //server2/share /media/tm cifs credentials=/home/jeff/.smbcredentials, _netdev,uid=jeff,gid=jeff,file_mode=0777,dir_mode=0777,iocharset=utf8 ,sec=ntlm 0 0 I increased logging to level "3" and here is what's going on when the first Flush error occurs (sorry about the formatting, Gmane is limiting each line to 80 chars): Jan 31 06:17:36 Server1 kernel: [70838.026873] /build/buildd/linux-3.11.0/ fs/cifs/connect.c: RFC1002 header 0x23 Jan 31 06:17:36 Server1 kernel: [70838.026879] /build/buildd/linux-3.11.0/ fs/cifs/misc.c: checkSMB Length: 0x27, smb_buf_length: 0x23 Jan 31 06:17:36 Server1 kernel: [70838.026889] /build/buildd/linux-3.11.0/ fs/cifs/transport.c: cifs_sync_mid_result: cmd=5 mid=34092 state=4 Jan 31 06:17:36 Server1 kernel: [70838.026893] /build/buildd/linux-3.11.0/ fs/cifs/file.c: CIFS VFS: leaving cifs_strict_fsync (xid = 2694478) rc = 0 Jan 31 06:17:36 Server1 kernel: [70838.027602] /build/buildd/linux-3.11.0/ fs/cifs/file.c: CIFS VFS: in cifs_strict_fsync as Xid: 2694479 with uid: 1000 Jan 31 06:17:36 Server1 kernel: [70838.027606] /build/buildd/linux-3.11.0/ fs/cifs/file.c: Sync file - name: 1c datasync: 0x0 Jan 31 06:17:36 Server1 kernel: [70838.027610] /build/buildd/linux-3.11.0/ fs/cifs/cifssmb.c: In CIFSSMBFlush Jan 31 06:17:36 Server1 kernel: [70838.027614] /build/buildd/linux-3.11.0/ fs/cifs/transport.c: For smb_command 5 Jan 31 06:17:36 Server1 kernel: [70838.027618] /build/buildd/linux-3.11.0/ fs/cifs/transport.c: Sending smb: smb_len=37 Jan 31 06:17:36 Server1 kernel: [70838.027875] /build/buildd/linux-3.11.0/ fs/cifs/connect.c: RFC1002 header 0x23 Jan 31 06:17:36 Server1 kernel: [70838.027882] /build/buildd/linux-3.11.0/ fs/cifs/misc.c: checkSMB Length: 0x27, smb_buf_length: 0x23 Jan 31 06:17:36 Server1 kernel: [70838.027896] /build/buildd/linux-3.11.0/ fs/cifs/transport.c: cifs_sync_mid_result: cmd=5 mid=34093 state=4 Jan 31 06:17:36 Server1 kernel: [70838.027900] Status code returned 0xc0000008 NT_STATUS_INVALID_HANDLE Jan 31 06:17:36 Server1 kernel: [70838.027906] /build/buildd/linux-3.11.0/ fs/cifs/netmisc.c: Mapping smb error code 0xc0000008 to POSIX err -9 Jan 31 06:17:36 Server1 kernel: [70838.027910] CIFS VFS: Send error in Flush = -9 Jan 31 06:17:36 Server1 kernel: [70838.027915] /build/buildd/linux-3.11.0/ fs/cifs/file.c: CIFS VFS: leaving cifs_strict_fsync (xid = 2694479) rc = -9 Jan 31 06:17:36 Server1 kernel: [70838.027981] /build/buildd/linux-3.11.0/ fs/cifs/xattr.c: CIFS VFS: in cifs_getxattr as Xid: 2694480 with uid: 1000 Jan 31 06:17:36 Server1 kernel: [70838.027985] /build/buildd/linux-3.11.0/ fs/cifs/dir.c: name: \afpd.log Jan 31 06:17:36 Server1 kernel: [70838.027989] /build/buildd/linux-3.11.0/ fs/cifs/xattr.c: Security xattr namespace not supported yet Jan 31 06:17:36 Server1 kernel: [70838.027992] /build/buildd/linux-3.11.0/ fs/cifs/xattr.c: CIFS VFS: leaving cifs_getxattr (xid = 2694480) rc = -95 Any suggestions of how to work around this or how I could provide more info?
